Product Introduction
The Roller Type Smoke Curtain is a new passive fire protection facility independently developed by our company for modern complex building spaces. Unlike traditional fixed drop-type smoke curtains, the roller type is normally rolled up and concealed inside a dedicated housing without occupying the visible headroom of the building. In the event of a fire, upon receiving signals from the fire control system, the curtain unfolds rapidly under gravity or electric drive to form a rigid smoke barrier.
Inheriting the structural essence of our classic fixed smoke curtains, the roller type has been technically upgraded in terms of bottom edge finishing and main body materials. Its bottom edge is embedded with aluminum angle trim to ensure flat vertical hanging. The main body adopts high-strength fireproof decorative board as the base material, which fully meets stringent fire and smoke resistance requirements while maintaining interior aesthetics when fully deployed. Featuring an exquisite structural design and high safety reliability, this product complies fully with national mandatory standards for smoke curtains and has obtained official type inspection reports for fire protection products.
Core Material Analysis
The stable fire-resistant performance of the Roller Type Smoke Curtain relies on its sophisticated material configuration:
Main Smoke Barrier Fabric / Fireproof Decorative Board
As the core smoke-proof layer, it adopts specially treated fiberglass coated fabric or high-strength inorganic fireproof fabric. The material is flexible and foldable at room temperature, ideal for rolling storage. Under high fire temperatures, it features extremely low thermal conductivity, non-combustibility, non-melting performance and zero toxic smoke emission. It can maintain structural integrity for 0.5 hours up to several hours, effectively blocking the spread of high-temperature toxic smoke.
High-Strength Aluminum Angle Trim
Adopting the mature craftsmanship of fixed smoke curtains with aluminum angle trimming under fireproof boards, the base of the roller curtain uses high-strength aluminum alloy profiles for counterweight and edge finishing. This ensures the curtain hangs perfectly vertical and taut during descent and static state, avoiding shaking caused by air flow. It also serves as a counterweight to guarantee smooth and full gravity drop under power failure and other emergency conditions.
Guiding & Fixing System
The top is equipped with a fixing clamp system made of premium aluminum angles, firmly anchored to building ceiling beams or floor slabs via high-strength fasteners. Anti-fall tracks are installed on both sides to prevent deviation and derailment during lifting and lowering.
Base Housing
Fabricated from cold-rolled steel plate or galvanized steel plate with plastic-sprayed finish. The surface color can be customized to match interior decoration styles (usually white or silver-gray), enabling it to blend seamlessly with suspended ceilings and beam bottoms for an invisible daily appearance.
Precautions & Maintenance Guidelines
To ensure the Roller Type Smoke Curtain can deploy reliably and function effectively in emergencies, the following regulations must be strictly followed during installation and operation:
Though the roller design well avoids overhead pipeline conflicts, the space beneath the descending path of the bottom aluminum trim must be precisely measured before design and installation. No ventilation ducts, lighting fixtures, cable trays or other protrusions are allowed on the descent route. The curtain must drop unobstructed to the designed safety height (normally no less than 0.5 meters above the ground to prevent personal injury).
Roller smoke curtains are generally linked with the Building Fire Alarm System (FAS). Daily inspection shall ensure accurate signal transmission from smoke/heat detectors to the control box. Meanwhile, manual button control and emergency gravity drop function upon power failure must be retained, with regular testing to guarantee sensitivity and effectiveness of backup activation modes.
Dust accumulation in guide rails may increase descending resistance in factories, underground garages and other dusty environments. The operator shall clean the rails quarterly to prevent foreign body jamming. Ordinary lubricants are prohibited to avoid dust adhesion; dedicated silicone-based lubricants shall be used if lubrication is required.
Fireproof decorative boards and smoke barrier fabrics are vulnerable to physical scratches and punctures. Climbing on the curtain or hanging heavy objects on it is strictly prohibited during daily cleaning or overhead pipeline maintenance. If tearing, scorch marks or large-area oil contamination are found on the curtain surface, contact the manufacturer for immediate replacement. Do not repair with adhesive privately, as this will impair fire resistance performance.
In accordance with fire protection regulations, building fire protection facilities shall undergo a comprehensive professional inspection at least once a year. Qualified fire maintenance personnel shall inspect motor insulation, limit switch accuracy, descending time (normally within 60 seconds) and smoke tightness of the curtain in full evaluation.
Application Scenarios
With its concealed standby & smoke-blocking on activation feature, the Roller Type Smoke Curtain is perfectly suitable for scenarios with strict requirements on floor height and interior aesthetics, including open office areas in large office buildings, atriums and walkways of high-end shopping malls, auditorium ceilings of theaters, as well as modern industrial plants and underground garages with complex overhead pipeline layouts.
